Lincoln was trying to appeal to Southern voters by picking Andrew Johnson as his running mate. These two men were actually very different politically speaking. Lincoln was a Republican, Andrew Johnson was a Democrat. Lincoln was from the Midwest US, Andrew Johnson was from Tennessee.
Lincoln knew that having a Democratic Vice President who once represented a Confederate state (Tennessee) would allow his presidency to appeal to a wider range of voters.
1. Jacob Riis. In the late 1800s, the rapid growth of cities during America's second wave of industrialization produced serious problems. Overcrowding in huge apartment buildings known as tenements were unsanitary, and garbage accumulated in the streets, leading to the spread of disease. Poverty was common, and crime was a result. Jacob Riis was a Danish immigrant who took photographs of the horrible living conditions in New York City. His photos in "How the Other Half Lives" shocked Americans and resulted in many reformers campaigning for better water and sewage systems and vaccinations.
2. NAACP. The NAACP, or the National Association for the Advancement of Colored People, was formed in 1909. In the late 1800s and early 1900s, African Americans in the North and South faced discrimination. Even though slavery had been abolished by the 13th amendment in 1865, African Americans were denied basic rights. Many notable African Americans from this time period advocated for full equality, such as Booker T. Washington, Ida B. Wells, and W.E.B. Dubois. Dubois believed that under no circumstances should African Americans accept segregation, and he helped found the NAACP to help with attempts to gain legal and economic equality for African Americans.
3. Conservation. The protection and preservation of natural resources is known as conservation. One of the most prominent leaders of the conservation movement was President Theodore Roosevelt. A progressive president and an avid outdoorsman, Roosevelt began to protect America's natural resources by establishing some of the first national parks for future generations. Other progressive presidents, such as William H. Taft and Woodrow Wilson, also contributed greatly to conservation efforts in the early 1900s.
4. Jim Crow Laws. After the abolition of slavery in 1865, laws in Southern states were put into place to separate blacks and whites. These laws were called "Jim Crow" laws, named after a character in a song. Jim Crow laws required the separation of African Americans and whites in nearly any public place they might come in contact with each other. A famous court case in 1896, Plessy v. Ferguson enforced the concept of "separate but equal" facilities and institutions to segregate blacks and whites.
The oldest recognizable signs of permanent human habitation and urbanization go back abut 12,500 years -- sites like Jericho<span> and </span>Göbekli Tepe<span> both show persistent communities who had the resources to build permanent structures and enough surplus food and labor to support specialists -- however both of those sites also show that hunting remained an important component of the community's way of life. There are certainly other examples of permanent settlements from this same period scattered around, particularly in the region of modern Syria, Turkey, Armenia and Iraq. </span>
The PYRAMIDS AND THE GREAT SPHINX rise inexplicably from the desert at Giza, relics of a vanished culture. They dwarf the approaching sprawl of modern Cairo, a city of 16 million. The largest pyramid, built for the Pharaoh Khufu around 2530 B.C. and intended to last an eternity, was until early in the twentieth century the biggest building on the planet. To raise it, laborers moved into position six and a half million tons of stone—some in blocks as large as nine tons—with nothing but wood and rope. During the last 4,500 years, the pyramids have drawn every kind of admiration and interest, ranging in ancient times from religious worship to grave robbery, and, in the modern era, from New-Age claims for healing "pyramid power" to pseudoscientific searches by "fantastic archaeologists" seeking hidden chambers or signs of alien visitations to Earth. As feats of engineering or testaments to the decades-long labor of tens of thousands, they have awed even the most sober observers.
